Hi ! Climate Change and Global warming are the most important issues of environment these days. It has become a challenge for the scientists all over the world to solve the problem of global warming and climate change. Some 40 countries will issue stamps on climate change this year to show concern about this existing environmental problem on the earth.. The common theme is Preserve the Polar Regions and Glaciers. In March, Finland will issue a Miniature sheet on climate change. The Finnish issue on climate change is a two-stamp miniature sheet entitled Melting Glaciers. The sheet depicts a Polar sea in which pieces of melting ice shelf are floating. The stamps on the Melting Glaciers miniature sheet are round: one forms part of the background picture's sky and the other is part of the sea. In the middle of each stamp is a snowflake symbol, the campaign insignia used by all the issuing countries. The miniature sheet will be issued on 18 March 2009. Well Finland often issues unique stamps, I have written about them in my earlier posts. Here is a novel miniature sheet with two nice round stamps. This is all for Today !.......Till Next Post…..Have a Nice Time !...
Global Warming
Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.
Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). It is responsible for the conspicuous increase in storms, floods and ranging forest fires we have seen in the last ten years, though, say scientists.
Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years, even.
But it is not only about how much the Earth is warming, it is also about how fast it is warming. There have always been natural climate changes – Ice Ages and the warm intermediate times between them – but those evolved over periods of 50,000 to 100,000 years.
A temperature rise as fast as the one we have seen over the last 30 years has never happened before, as far as scientists can ascertain. Moreover, normally the Earth should now be in a cool-down-period, according to natural effects like solar cycles and volcano activity, not in a heating-up phase.
